Customize the background for your character appearance screen

Add manga-style word effects to attacks

Equip items to give your character special item-based attacks

Make use of the new Tekken Tunes mode to customize the BGM

Add aura and other effects to attacks

We have screens of those customization elements, and artwork and screens showing collaboration costumes designed by manga artists like Ito Oogure, Shigeto Koyama, Simon Bisley, Ryouji Minagawa, Mutsumi Inomata and Katsuya Terada, in the gallery below.
